摘　　要：通过对框架填充墙的施工过程进行调研发现,在实际施工过程中,大部分企业并没有按照规范规定的抗震构造措施进行施工。为研究该类结构是否能够满足抗震要求,采用有限元数值计算方法进行了模拟与分析,基于Ansys计算程序,分析了存在施工缺陷的框架填充墙在罕遇地震作用下的裂缝发展及破坏情况,并提出了加固措施;同时对加固后的结构进行了数值模拟分析,并与加固前的模拟结果进行了对比分析。结果表明:存在施工缺陷的框架填充墙结构不能满足"大震不倒"的抗震设防标准,进行加固后,框架填充墙表现出了良好的抗震性能,满足了抗震设防标准。The research on construction process of frame infill wall found that mast construction enterprises did not conduct the construction according to the specifications. In order to research whether the structure can meet the anti - seismic demand, the ANSYS finite element calculation program was adopted to simulate the filled wall that exists constructional deficiency to observe the destruction situation of the infilled wall. Then, the strengthening measures were put forward and numerical simulation of the strengthened structure was conducted and compared with that of unstrengthened one. The results show that： the infilled frame structure that exists constructional deficiency cannot meet the fortifying standard of ＂no collapse in strong earthquake＂, and the structure after strengthening has a good seismic performance, satisfies the seismic fortifying standard.
